Lymphatic System

What is bone marrow and its significance?

• A soft tissue inside bones that produces blood cells, including red blood cells, white blood cells, and platelets.

• A type of muscle tissue that helps in movement.

• A hard structure that protects the organs in the body.

• A fluid that circulates in the blood and helps in digestion.

What is the spleen's function in the lymphatic system?

• The spleen filters blood, recycles iron, and helps produce white blood cells.

• The spleen stores bile and aids in digestion.

• The spleen produces insulin and regulates blood sugar levels.

• The spleen is responsible for filtering lymph and producing antibodies.

What is the significance of the thymus in the lymphatic system?

• It produces antibodies to fight infections.

• It is where T-cells mature, playing a crucial role in the adaptive immune response.

• It filters lymph and removes pathogens.

• It stores red blood cells and platelets.

What are tonsils and their function?

• Tonsils are muscles that help in swallowing food.

• Tonsils are lymphoid tissues located in the throat that help protect against pathogens entering through the mouth and nose.

• Tonsils are glands that produce hormones for growth.

• Tonsils are bones that support the structure of the throat.

What is lymph fluid?

• A clear fluid that circulates through the lymphatic system, containing white blood cells and waste products.

• A type of blood that carries oxygen to the body's tissues.

• A yellowish fluid that is produced in the liver and helps in digestion.

• A thick fluid that is found in the joints and helps lubricate them.

What is the role of lymph vessels?

• To transport oxygenated blood throughout the body.

• To transport lymph fluid, which contains white blood cells, throughout the body.

• To absorb nutrients from the digestive system.

• To produce hormones that regulate metabolism.

What type of cells are responsible for fighting infections?

• Red blood cells

• Platelets

• White blood cells

• Nerve cells

What are lymph nodes?

• Small, oval-shaped structures that filter blood and produce red blood cells.

• Small, oval-shaped structures located throughout the body that filter lymph fluid and house immune cells.

• Large, round organs that store fat and produce hormones.

• Tiny, irregularly shaped cells that transport oxygen in the blood.

How does the lymphatic system aid in fat absorption?

• It absorbs fats and fat-soluble vitamins from the digestive system through specialized lymph vessels called lacteals.

• It transports oxygen to the body's tissues and removes carbon dioxide.

• It produces hormones that regulate metabolism and energy levels.

• It filters blood and removes waste products through the kidneys.

How do lymph nodes contribute to the immune response?

• They produce antibodies that directly kill pathogens.

• They trap pathogens and foreign particles, allowing immune cells to respond and initiate an immune response.

• They filter blood to remove toxins and waste products.

• They store nutrients and minerals for immune cells.
